2001 A4 1.8t AWM: Can't get all the air out of power steering system

Replaced power steering pressure and return lines on rack.
Followed service manual procedure for purging.
Basically it's jack up the front, lock to lock for a specific number of times.
Then put back down, start up and do lock to lock again for a specific number of times.
Go drive around.

Well....been driving around for a few weeks, still get whine in the power steering system.

What kind of experience have you folks had with doing this kind of work on the power steering system?
Thoughts?

I might be a little over full on the power steering reservoir, but likely by a few hairs if I remember correctly.
Could that be preventing full purging of air from the system?

I had continual issues with air in my S4's PS system about a year ago. Couldn't get it to bleed the air out, NO MATTER WHAT. PS worked fine though, other than the appearance of "high flow" in the PS reservoir:https://www.youtube.com/watch?v=ZiZIRzQxaEI

I had replaced the hose between reservoir and P.S. cooler with silicone, which didn't have the restrictors that the original hose had. Also installed a Meyle reservoir.
My problem was resolved by switching back to the original hose and swapping in a new Genuine reservoir.
